Decade/Diend.

Aside from Kamen Ride/Form Ride Cards, Decade/Diend cards were... basic.

Attack Ride Slash!
Attack Ride Blast!
Attack Ride Invisible!
Final Attack Ride!

Arsenal with forms is kind of hard. Decade uses Den-O to get his ass kicked by Kabuto Riders. Decade is winning his fight against Chinomanako and transforms into Den-O and starts losing and then tries to use a Den-O Finisher and it was so god damn slow that the kaijin was like "lol. -jumps out of way-" And in most cases, Decade Violent Emotion is much stronger than any of his Kamen Ride Cards, allowing him to use all Attack Ride Cards without the originating form equipped.
